<p>Have been googling an LVM question on Slackware and came across this great slackware tips and tricks with explicit instructions on tweaking a couple may apply: <a href="http://www.fprimex.com/linux/slackware/tips.html" rel="nofollow">link text</a></p>
<p>What run level are you using? I don't use KDE although its installed but sometimes Xserver blinks out and I alt ctrl till I get another terminal then shutdown as root. Are you using a laptop or desktop? Wireless keyboard or PS2? Caps lock blinking - batteries for the keyboard? $ps aux shows tty7 as root. For me first line is tty3 and tty1 the one i am using.
Do you have 3 or 4'initdefault'... Goto the above link it will walk you through your startup 'display manager' settings, edit /etc/rc.d/rc.4 and change the order of preferred display managers, so kdm is first. Let us know if it works ;)
